How to remove AnalyzerSystem adware

Also Known As: Ads by AnalyzerSystem
Type: Mac Virus
Damage level: Medium

What kind of application is AnalyzerSystem?

AnalyzerSystem is an untrustworthy application distributed via a fake Adobe Flash Player installer. After installing and analyzing the app, we learned that it is useless and shows unwanted advertisements. Thus, we classified AnalyzerSystem as adware.

AnalyzerSystem adware

AnalyzerSystem adware in detail

AnalyzerSystem displays intrusive advertisements designed to open deceptive websites asking to provide sensitive information, promoting potentially malicious apps, and other dubious pages. It shows banners, coupons, surveys, pop-ups, etc. It is also possible that clicking on ads displayed by AnalyzerSystem can cause unexpected downloads or even installations.

Another reason not to trust AnalyzerSystem is that it may be capable of accessing/reading sensitive information. We tested many apps similar to AnalyzerSystem and learned that some of them can read credit card details, passwords, telephone numbers, etc. Having AnalyzerSystem installed may cause problems related to online privacy, browsing safety, and other issues.

Adware in general

Advertising-supported applications bombard users with intrusive advertisements. Additionally, they can be designed to hijack web browsers and collect various information. Typically, apps like AnalyzerSystem are promoted and distributed using deceptive methods. Thus, users often download and install them inadvertently.

More adware examples are ComputingInvolve, BridgePro, and DockMode.

How did AnalyzerSystem install on my computer?

AnalyzerSystem is distributed via a fake installer. It installs after completing the installation steps. This installer is promoted on deceptive websites claiming that the installed version of Adobe Flash Player is out of date. Adware is often distributed in other ways as well.

Adware can be installed by clicking on deceptive ads or through software bundles. In the second case, users install adware after finishing installations without changing "Advanced", "Custom", "Manual", or similar settings available in installers containing additional apps.

How to avoid installation of unwanted applications?

Download applications and files from trustworthy/official websites and legitimate stores. Using unofficial pages, third-party downloaders, P2P networks, and similar sources is unsafe. Also, check downloaders and installers for unwanted apps and deselect them before downloading or installing software.

Do not trust advertisements appearing on suspicious websites or allow such pages to show notifications. If your computer is already infected with AnalyzerSystem, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
